LOCK-ACTUATING MECHANISM.

Specification of Letters Patent.

Patented Nov. so, 1915.

Application filed. April 30, 1914. Serial 11033552 1.v

To all whom it may concern:

Be it known that I, GEORGE Angeles, in the county of Los Angeles andState of California, have invented certain.

new and useful Improvements in Lock-Actuating Mechanism, of which thefollowing is a specification.

My invention relates to locking mecha nism and particularly to mechanismfor throw ng a plurality of bolts in different d1 rections, thismechanism being particularly adapted for use with the form of combineddoor and window shown in my pending application Serial No. 807,527,filed on' the 18th day of Dec, 1913. In this application for patentthere is illustrated an improved form of window which also may be usedas a doorand in which the window (or door) is provided with pintles onopposite sides which are adapted to be projected into the window casingso that the window may be side, as may either from the right side orleft be desired. In this prior application these pintles were shownasbeing opened detachable and shiftable from one side of the window casingto the other. In this application there is also shown a locking devicewhereby the window might .be locked in the casing.

One object of my invention is the provision' of locking means adaptedparticularly for use in connection Withthe above de-, scribed window, soconstructed as to con trol the operation of pivotbolts or pintles onopposite sides of a window or door and so control the operation of boltswhereby" the door or window may be locked tothe window casing, it beingunderstood, however, that the pivot bolts or pintles them-' selves actas looking bolts under certain circumstances.

A further object of the invention is to so construct the lockingmechanism above referred to,'that it may be applied toa large variety ofstructures and usedfor throwing or retracting a plurality of bolts.

Still another object of the invention is to so construct the lockingmechanism, above referred to, that two actuating devices or keys must beused to completely retract all of the bolts, one of these lockingdevices A. FAIR, citi zen of the United States, residing at Losactuating the longitudinally movable bolts which orm the pintles' or.pivot bolts when the device is used for a window or door and theothercontrolling the latching bolt.

- A further object of the invention is .to

simplify loc'lring'mechanism of the character described, reduce itscost, render it easy 1 of operation and reduce liability of the partsgetting out of order.

Other ob ects will appear in the course of the following description.

Myinvention is illustrated in the accoma pan ying drawings wherein Vigure 1 is a iront elevation of a piv oted window of the easement type,the sashframe being shown partly in section so as to sl owrthe-boltmechanism within the sashiframe.

Corresponding and like parts are referred to: in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

'Before describing the detailed construction of the locking mechanism, Iwill first describe one of the structures to which the locking mechanismis peculiarly adapted, this beingthe window structure illustrated anddescribedin detailin my pending application for patent above referredto.

V In Fig. 1 is' illustrated a window, the frame of this window includingthe Vertically disposed members 3 within which b possible to project thepintles 13 and 14 on there is mounted an exterior sash-frame comprisinghollow side bars 4, illustrated in detail in Fig. 2. The outer faces ofthese side bars 4 are formed .by curved plates 5 which are illustratedas hinged at 6 so as to open when desired to permit the insersash-framewithin which the sliding sashes are mounted is of the easement type andis, therefore, pivotally connected tothe frame of the window. To thisend the window frame includes theuppen and lower transverse members 10and 11, the upper and lower plates respectively, of which, are formedwith sockets 12 for the inserion of pintles 13 and 1 1. The plate 5 isalso perforated at 15 for the passage of laterally projectable boltswhich engage with the face of the window casing 2.; With theconstruction of window illustratedin Fig. 1 it is one side of the windowso that the window will. be pivoted upon that side and retract thepintles on the other side of the window so that this side of the windowmay be free to move. If it be desired for any reason that the windowshall open in a reverse direction, then the first named set of pintlesare withdrawn from engagement with the window casing and the secondnamed set of pintles is projected. It is-for the purpose of providingmeans for withdrawing these pintles and also withdrawing the latchingbolts which engage the side members of the window casing that I haveprovided mechanism illustrated in Figs. 2, 3, i and 5, it being one ofthe objects of nay-invention to so construct this mechanism that themeans for projecting or retracting the pintle bolts 13 and let will beindependently operable from the mechanism for projecting the latchingbolts. The mechanism for this purpose is most clearly shown in Figs. 4and 5. For the support of the bolt actuating device the plate 5 isformed on opposite sides with the inwardly projecting annular bearings16 and 17, respectively. Mounted within the annular bearing 16 is anannular sleeve 17 the outerend of which extends-out through the front ofthe casing and is formed with a knob 18 whereby the sleeve may berotated. The sleeve at its innerend is countersunk asat19 and disposedwithin this countersink is a barrel 20 illustrated in detail in Fig. 5.Disposed within the barrel 20 is a shaft 21, the endsof which are formedwith longitudinally extending relatively short nal axis.

kerfs or grooves 22 and 22''. This shaft has a length equal to thebarrel 20. The extremity of the barrel 20 projects slightly into athinible 23 which is rotatably mounted within the bearing member 17, theinner end of this thimble being outwardly flared as at 2%. It will thusbe seen that the barrel 20 is mounted for rotation around itslongitudinal axis and that the shaft 21 is also mounted for rotationaround its longitudi- The barrel 20 is longitudinally slotted atdiametrically opposite points at both ends as at 25 and 26 and at itsmiddle.

is formed with an arcuate slot 27 which alineswith a screw threadedperforation 28 formed in the shaft 21.

A screw 29 extends through the sleeve 17 and engages the adjacent end ofthe barrel 20 so that the sleeve 17 and the barrel 20 rotate together.Mount-ed upon the barrel 20 is a, collar 30.. This collar is providedwith a slot 31 through which a screw 32 passeswhich enters the slot 27and engages the perforation 28 in the shaft 21. The collar 30 has atubular extension 33 projecting tangentially from one side and intowhich the slot 31 opens and mounted in this tubular extension 33 isalatching bolt 3 1. The pin 32 which is carried by the shaft 21 projectsthrough the slot 27 of the barrel 20 and the slot 31 of the collar 30and is connected to the bolt 34 by means of a link 35 and disposedwithin the extension 33 between the bolt 31 and a stop 36 is a coil.JDPlDL 37 which normally tends to project t e bolt. It will be obviousnow that a rotation of the shaft 21 in a counter-clockwise direction inFig. 3 will cause a retraction of thebolt'3at against the action of thespring 37, the collar 30 remaining stationary.

Mounted upon the collar 30 and extending over the slot 31 is an arcuatespring 38, the extremity of which is formed with a detent tooth Thistooth is adapted to engage over the head of the screw 32, as illustratedin Fig. 3, when the shaft 21 is rotated so as to retract the bolt. Thespring 38 is of sufficient strength to hold the bolt 34 retracted whenthe parts are in the position shown in Fig. 3, but yet not prevent theproper manipulation of the bolt to project it. It will be seen that whenthebolt is projected the detent 39 will engage behind the head of thescrew 38 and thus resist the inward movement of the bolt. The spring 38is held to the collar 30 by means of a screw 10 extending into theperforation 41 formed in the collar 30. The extremity of the extension33 is intended to be engaged with the perforations 15 in the plate 5through which the bolt is projected, as illustrated in Fig. 3, and thisextension merely acts as a guide for the bolt.

For the purpose of operating the pintle bolts 13 and 1 1 I mountupon'the barrel 20 the collar 42 illustrated in detail in Fig. 5 thiscollar being held in place on the barrel 20 by means of a set screw 43or in any other suitable manner. The collar 42 is providedat oppositepoints in its middle with pairs of arms 43 between which the inner endsof the pintle bolts 13 and Id are pivotally supported, as illustratedclearly in Fig. 2. It will be obvious now that a rotation of the barrel20 in one direction through the action of the knob 18 will withdraw thepintle bolts from their projected position and that a rotation of theknob 18 in the other direction will act to project the pintle bolts. I

Mounted upon thecollar 42, asillustrated in Fig. 2 is a spring detent426, the extremity of which is formed with a slightly depressed portionadapted to engage with shallow re-' cesses l7 and 48 formed in thebearings 17.

,This spring 436 forms a tooth holding the collar set in either of itsrotated positions. For the purpose of operating the shaft 21 I disposewithin the bore of the knob 18 and the sleeve 17 a spindle L9,'he'eXtremit-y of which is provided with a. small knurled knob 50. Theinner end of this-spindle 49' is formed withoppositely disposed teeth 51projecting longitudinally of. the spindle, which teeth are adapted toengage in the groves 22 formed atone end of the shaft 21.

As before stated the barrel 20 is provided at one 'end with slots 26 andatthe opposite end. withslots 25. This permits the barrel 2Q andtheshaftQl to be operated from the exterior by means of keys A and B, asshown in Fig. 4; Key A is formed with the relatively widely spacedlongitudinallyextend ing. teeth a. which are, adapted to engage with thenotches 25.

of such width as to engage the'grooves 22 By inserting the key A,therefore, the barrel 20 may be rotated to thereby retract or projectthe pintle bolts, and by inserting the key, B the shaft 21 may berotated to thereby project or retract the latching bolt 3i.

As seen in Fig. 2 there is a locking mechanism of the characterheretofore described at each side of the window engaging with theadjacent casing wall. In one of these locking devices the pintles areprojected so as to form a pivot forthe window while the latching bolt3a. is normally retracted. At the opposite side of the window, that is,the side edge which is free, the pintle bolts are normally retracted andthe latching bolt 34: only projected when the window is closed to holdthe window shut. 1

As before stated, I primarily design my mechanism for use with thewindow illustrated in Fig. 1, where it may be desired to The key B isprovided with the teeth 5 whichare so positioned and change the pivotalcenter of the window from one side to the other. In this case it is onlynecessary to removea screw 52 which passes through a slot 53 formed inthe bearing 16 and which also passes through'a slot- 54 formed in thesleeve 1'? and which engages With the spindle i9, thus holding thespindle in place and also holding the sleeve 17 in place and preventingany pulling out of the sleeve or spindle. By removing this bolt 52 thesleeve l'i niay be withdrawn, as may also the spindle a9 and sleeve maythen be shifted from one of the locking devices to the other, thuspractically rendering one of the locking devices inoperative and theother operative. It will of course beobvious that the knob 18' and thespindle 49 are to be disposed on the free or movable side of the window,there beingno knob upon the locking mechanisnron the,

other side of the window which will prevent accidental tampering withthe pintles or with the latching mechanism; If it. be desired, however,to withdraw the pintles,

upon the pivot side of the window so as to permit the window to be takenout, for 'instance, or if it be desired to throwthe latching bolt. onthe pivotside of the window, then thelshait 21 and barrel 20 on thatside of the window may be operated by means of keys of thestype shown inFig. 4 and lettered A and B. If it be desired to loc the win dowparticularly securely, it is obvious that rior ofthe compartments l thatI hinge the plate 5.

In Figs. 6 and? I show my invention as applied to door and I wish itdistinctly'understood that while I have shownit used on a house door,the invention may equally well be applied to doors of any construction,such as doors of vaults, safe deposit boxes,

door and D the door-frame. As illustrated, thesill and 'lintel of thedoor are provided with sockets 12 of precisely. the same form of thesockets 12, heretofore described. j The dooris recessed to receive thelocking mechanism which is the same as that described,

7 or like. structures. In these figures C designates the this lockingmechanism being providedwith j the vertically extending pintle bolts 13?and li 'The locking mechanism is controlled by" knobs and keys inprecisely the sameman- -l neras shown in Figs. 2, and it, and hasexactly the same construction;

In order topermit the door to be rotated it can be set in a slightlydeep recess and rotated flat against the wall and I form the sockets 12"arcuate, as illustrated clearly in Fig. 6 so that when the door swingsinto the dotted line position shown in Fig. 6, the pintles 13 and 14 onthat side of the door will travel through the arcuate slot and thuspermit the door to be shifted flat against the wall. It will be seenthat the arcuate slot l2 on the free side of the door does not preventthe pintle bolts from acting to lock the door when they are projected.

In Fig. 8 I show a modification of the construction shown in Fig. 4 inwhich the outer barrel is adapted to project the latching bolt while theinner shaft is adapted to project the pintle bolt, this inner shaftbeing entirely key actuated so as to prevent any accidental throwing ofthe pintle bolts. In this form of the device the plate 5 is provided on0pposite sides with inwardly projecting bearings l6 and 17, aspreviously described. Disposed within the bearing 16 is the sleeve whichhas formed with it the knob 56 where by the sleeve may be manuallyrotated. Disposed within the innerend of this sleeve 55 is thebarrel 57to which the sleeve is fastened by means of the set screw 58 so that thebarrel rotates with the sleeve. Stir-- rounding the barrel is the collar59 which has the same form as the collar 30, previously described, andoperating through the slot 60 in this collar is the pin 61' whichcorresponds in every respect to the pin 32, previously stated, exceptthat it is fastened on the barrel and not upon the central shaft. Thispin 61 is operatively connected to the bolt 62, as shown in Fig. 11, sothat a rotation of the handle 56, the sleeve 55 and the barrel 60 willcause a projection or a retraction of the bolt. Also mounted upon the 1sleeve 57 is the collar 63 which corresponds to the collar l2 and isoperatively connected to the upwardly and downwardly extending pintlerods 13 and lt, in the same manner as is the collar 4:2; For the purposeof operating this collar 63 and thereby throwing the pintle rods in orout of operative position, the collar is connected to the central shaft64 by means of the pin 65 which passes through the slot 66 formed in thecollar 63.

The shaft 64 has exactly the same form as the shaft 21 and is notched atits ends as at 67 for engagement by a key. A thimble 68 is disposedwithin the bearing 17 and supports the forward end of the sleeve 57. Itwill be obvious now, that upon a rotation of the shaft 64: thepintlebolts will be retracted or projected and that upon a' rotation of thesleeve 57 thelatching bolt will be projected or retracted. The latter isaccomplished by rotating the knob 56 but rotation of the shaft 64: canonly be accomplished by. means of a key such as the key 13 in Fig. 4having lugs Z) which will engage the notches 67 on the ends of theshaft. Thus, while the latching bolt may be manually projected or retracted the pintle bolts cannot be actuated except through the use of akey.

In Figs. 9 and 10 I show my invention as applied to a safe deposit boxor like structure. In these figures 69 designates the wall of a safedeposit vault and 70 designates the box which is slidable into thecompartment 71 and out from said compartment. This box has a front wall72 and an intermediate wall 73 and a rear door 74 which can only beopened when the box is withdrawn. The box is held within the compartment71 by means of vertically extending bolts 75 and 76 and the laterallyprojectable latching bolts 77. The operating mechanism for these bolts75, 76 and 77 is designated generally 78 and is of exactly the sameconstruction as the operating mechanism illustrated in Figs. 2, 3 and texcept that the mechanism is made to be operated entirely by keys in themanner shown in the right hand side of'lTig. 4 and is not operated byknobs. The bolts and the bolt operating mechanism are all contained inthe space between the front wall 7 2 and the intermediate wall 73. Inthis case it will be noticed that the members 75 and 76 both operate aslooking bolts and not as pintle bolts and that two keys are necessary tooperate the bolt throwing mechanism, one key operating the laterallyprojecting bolt and the other operating the vertically projected bolts.It will be obvious that a set of four keys, may be used so as tooperatethese bolts, one pair for each of the locking mechanisms, the keys beingdifferent so that thus an additional security is provided.

It will be seen from what has gone before that while I have designed myoperating mechanism primarily for use with the door or window for thepurpose of throwing or retracting pintle bolts and latching bolts, yetit may be largely adapted for a number of other purposes andit is forthis reason that I have illustratedthe applicationof my device to a safedeposit box where the box is entirely withdrawable from the bolt. Thesame locking means, however, may be used upon a hinged door, if desired.

Vhile I have illustrated what I believe to be the best form of myinvention Ido not wish to be limited to the detailsof construction as itis obvious that many changes might be made without departing from thespirit of invention.

It will be seen that I have provided a lock which is also a hinge soconstructed that by the use'of two of these hinge locks the pivotal'point of the door may be shifted from one side to the other, if desired.Further, it will be seen, that when in use, and when both of the lockingor bolt-operating mechanisins are used the door is held at siX points.

Further, that I provide a door locking and hinging constructionrequiring the use of two keys and operating members in order to secure acomplete operation of the mechanism. This gives eXtra security to allbuildings and at the same time permits of the window or door being swungfrom either side. The lock or hinge is concealedwithin the door itself,nothing but the keyhole or the knob whereby the device is operated beingvisible from the outside.

One of the principal features of my invention lies in the fact that thedoor or window can be unhinged in a moment so that the whole door may beremoved without the necessity of taking off the hinges. This permits theready removal of the door to allow furniture, pianos, or like bulkyobjects to be moved through the doorway.

A further advantage of the construction lies in the fact that when allof the bolts are shut the door is shut tight at every point. This keepsthe doors from warping inwardly at the upper and lower corners above theusual lock. Again it must be reiterated that while I have illustrated myinvention as applied to a door or window or safe deposit boX, that it isnot limited to this application, as it may be used for safety doors, forboxes, trunks, lockers, or in many other situations.

Having thus described the invention what is claimed as new is 1.
